The patient has pellucid degeneration and the lens would decenter slightly inferiorly which resulted in a small amount of residual glare/halo. This fit was more challenging due to the expectations/needs of the patient. Patient was wearing glasses before, and is extremely happy to be in contact lenses that work for most activities. He states he is happy overall, but still has some halos/glare at night. The patient wears the lenses 12-14 hours a day. At this visit the patient preferred a combo of the UH-FC OD and original UH OS because the shadowing was minimized. When the UH-FC lens came in the patient preferred the standard UH, although acuity was equal. Patient wanted to compare glare/halo between the two lenses. He persisted and an UltraHealth-FC was tried OS. I advised the patient he was doing well and not to change OS. At follow-up the patient was happy OD and wanted to try UltraHealth FC (UH-FC) on his left eye (he was already wearing UltraHealth (UH). Patient stated clarity was great but glare/halo was annoying. The original lens OD, UltraHealth, at follow-up was minimally tight fitting and inferiorly decentered. He feels his vision has improved with the contact lenses. The patient is happy with the acuity and ability to wear contacts. Patient is also in a band and had high visual demands for night driving and dim environments. The patient had corneal cross linking on both eyes and presented needing an improvement to vision for work. The patient is a firefighter/paramedic who was diagnosed with pellucid marginal degeneration OU. Kristi Rhodes, Schwartz Laser Eye Center, AZ Since they are more stable within the eye, and because they mask virtually all corneal irregularity, these contact lenses offer superior optics & vision compared with any other contact lens options.ĭo you have irregularly shaped corneas, dry eyes, or a corneal disease? Talk with us about the benefits of scleral contact lenses for your vision correction! Many dozens of patients with hard-to-fit eyes or numerous corneal diseases have experienced great success by using scleral lenses here at Mt Baker Vision Clinic.OD: Dr.
You don’t need to worry about the contact lens accidentally falling out of the eye. Since the scleral lenses are bigger in size, they also stay in the eye better. Sclerals take a bit more time to insert and remove compared to most contacts, and require particular solutions to clean and fill the bowl of the lens with prior to insertion. They are also more cumbersome to use (there’s always a catch, right?). We typically use scleral lenses that are 15.8mm in diameter, but that depends based on individual corneal sizes and conditions. How Do Scleral Lenses Compare with Other Types of Contact Lenses? From both an optics and a corneal comfort perspective, we’ve literally seen people here in Whatcom County have their lives changed due to scleral lenses. For people with dry eye disease, incomplete lid closure, graft-host disease, or other reasons for poor corneal surface health, this can vastly improve visual clarity, as well as eye surface health and comfort. Second, the back surface of the scleral lens is fit 125-300 microns above the cornea, leaving a reservoir of lubricating saline solution continuously bathing the cornea in fluid. This allows for exceptional clarity of vision, even for people with irregular astigmatism, keratoconus, pellucid marginal degeneration, post-Lasik corneal ectasia, radial keratotomy, post-traumatic scarring, post-corneal transplant, or other forms of poor optics. First, scleral lenses create a smooth optical surface, covering over all irregularity in the cornea. There are two huge benefits to this design.
